This invention relates to embroidery hoops and is primarily concerned with a simple and novel construction of embroidery hoop whereby the meeting end portions of the hoop,

one at each side of the parting therein, are properly guided with respect to'each other by a very simple construction which reduces the cost of manufacture and at the same time provides a particularly useful and advanta geous structure for manufacture and assem- An understanding of the invention for the attainment of the ends stated may be had from the following description taken in connection with the accompanying drawing, in

which,

Fig. l is an elevation illustrating the invention as applied at the end portions of the hoop at each side of the parting therein.

Fig. 2 is a fragmentary longitudinal section therethrough.

Fig. 3 is a transverse vertical section through the hoop adjacent one end thereof.

F ig. 4 is an inner elevation showing the invention applied to a cork lined hoop.

F ig. 5 is a fragmentary longitudinal section therethrough, and I Fig. 6 is a transverse section through the hoop shown in Fig. 4 near one end thereof.

Like reference characters refer to like parts in the different figures of the drawing.

The embroidery hoop is made of sheet metal in circular form and includes a Hat web l at each edge of which, in the form shown in Figs. l to 3 inclusive, the metal is formed into outwardly turned rolls 2 entirely around the length of the hoop. Short portions 3 of the rolls at the respective ends of the hoop having their inner edges Cut away to provide for the insertion of a plate 4 hereafter described.

A plate 4 of flat metal of the form best shown in Fig. l is located between the chan-v nel guides 3 of both ends of the loop and extends across and bridges the gap or parting therein. The side edges 4a of the plate are turned upwardly and enter the channel guides 3, as shown in Fig. 3, while the ends of the plate are substantially of U-form, there being i. provided by this construction a very secure leach other and terminate in oppositely screw and firm connection between the ends of the ring, yet one which permits a free sliding movement of the plate with respect to the ring ends or vice versa.

Any practical means may be used for drawing the ends of the hoop toward each other. In the form shown in Figs. l to 3 inclusive, loops 5-V arc struck outwardly from the webs l adjacent each end of the plate 4 and a coiled spring 6 under tension is connected at 60 each end with said loops, the tendency of the spring being to draw the two ends of the hoop toward keach other. It is evident, however, that the ends of the hoop may be spread apart readily by exerting force sulii- G5 cientvto stretch the spring, but that as soon as the force is released the spring will draw the ends of the hoop toward each other and contract the hoop against work located within it. f

In Figs. 4 to 6 inclusive, an application of the invention to a different form of hoop is shown. In this case the rolls 2 and the channel guides 3 are turned inwardly instead of outwardly, as in the construction first dcscribed, and the bridging plate 4 is located at the innerside of the web instead of the outer side. The hoop is lined with a cork lining 7 which at its ends is reduced in thickness, as indicated at 7, the amount of reduc- SO tion being equal to the thickness of the plate 4.

In this form of the application of the invention there is shown a different manner of drawing the ends of the hoop toward each S5 other. Brackets 8 are attached to the outer sides of the web 1 a distance from each end of the hoop which extend outwardly for a short distance and are then turned toward threaded Shanks 9. A turn buckle 10 is located between and connected with the shanks 9. Turning the turn buckle serves to either draw the ends of the hoop toward each other or separate them in accordance with the direction in which the turn buckle is operated.

It is evident that with this construction the hoop ends are of identical form. It is not necessary to make one of a form to tele-A scope within the other as has been very sont properly guide the same in their movements` toward or away from each other but also i`nsnres that the material held within the hoop shall not bunch up and extend through the gap or parting in said hoop. This construction o f embroidery hoop has proved very satisfactory in service. The invention is defined in the appended claims and is to be considered comprehensive of all forms of structure coming within their scope.

I'cl'aim:

1. A parted embroidery hoop of metal having a Hat web and rolled edges, a bridging plate offflat metal located between said rolled edges and relatively movable with respect to both ends of the hoop bridging the gap between the ends of said hoop7 and means for drawing the ends of said hoopk toward each other.

2. An embroidery hoop of -metal having a parting at one side therein and formed with guides at its side edges at each side of the parting, means attached to thehoop at a distance from each end thereof for drawing the ends together and a rectangular plate of flat metal located between the guides andbetween the attachments of said means bridging the gap between adjacent ends of the hoop at seid parting3 said plate being movable relative to both ends of the hook,

3. An embroidery hoop having a parting therein at one side, said hoop being formed with return bent guides at its edges, a flat bridging plate extending across said parting from one end of the hoop to the other, having its edges curved' away from the plane of the plate andI received in said guides, and means for drawing the ends of the hoop toward each other.

ln testimony whereof I my signature.
